It's a model DFW-150CF. I saw on the Internet that there migh be a kit using John guest fittings, seems like that would work better than the current setup. I don't believe there is a solenoid valve, there is a small pump. Maybe there is a diaphragm in the pump that is leaking by?

If you're wondering about any upgrades that AJ Antunes/Roundup may have available, you should call them. Sometimes a printed manual is dated and won't reflect such things.

I've never worked on one of these steamers. However, I did perused their manual. You can go to http://www.partstown.com/ and use options in upper-right corner to "Find Equipment Manuals" and download yourself a PDF version of the Service & Parts Manual.

Looks like it probably needs a water pump kit (pn: 7000850), which includes a tube kit with it. The parts breakdown doesn't show any rebuild kit for the pump.

Make sure your customer hasn't lost the water tank filter assembly (pn: 0010159) and that they know to remove and clean it monthly per the manual. If it's missing, I suspect that would cause premature failure of the pump.

Check to see your water pressure is no more than 25 psi , if so they sell reg/filter kits that go with steamers

You are correct regarding water pressure to a model DFW-250, where the "2" denotes direct water hookup. It uses a solenoid valve to control water flow. Incoming water pressure should be regulated to below 30 PSI. AJ Antunes/Roundup does sell a regulator kit for that application.

However, Sean's steamer is model DFW-150, where the "1" denotes self-contained water tank, and uses a built-in pump to deliver the water to the steam chamber.
